TECHNICAL FIELD

The presently disclosed embodiments are related to verification of media content. More particularly, the presently disclosed embodiments are related to methods and systems for verification in fixed size media content or dynamically generated media content.

BACKGROUND

Today, media content is used in a variety of applications. The examples of the media content can be both audio and video contents. There are certain features associated with the production and broadcasting of the media content. Currently, due to the use of new technologies, evolving industry standards and the use of open architecture in the development of the media content, verification of the features associated with the production and broadcasting of the media content is essential for ensuring a quality broadcasting of the media content. As a result, the media content developers, providers, broadcasters and operators need to carry out quality checks to verify the media content.

The media content developers, providers, broadcasters and operators apply various media content verification methods known in the art on the media content. However, such methods are generally limited in their performance since the quantity of the media content is generally very large and is to be verified for quality checks 24*7, however the content verification occurs on a single core which makes the verification process considerably slow as it takes a substantial amount of time for verification due to presence of large quantity of media content.

In order to address this problem of slowness in verification process, media content verification methods have been developed in which at least the portion of the verification process is performed on the multiple cores. One of the known methods for verifying the media content is a slice-based method. In the slice-based method, a frame of a plurality of frames of the media content is broken into multiple slices. The parsing of each of the multiple slices of the frame of the plurality of the frames of the media content is performed on a single core; however the decoding of each of the multiple slices of the frame of the plurality of frames of the media content is performed simultaneously on different cores. The slice-based method is limited by the factor that the improvement in the performance of the verification process is dependent on the number of slices. Thus, the gain (dependent on the performance) is not able to increase linearly with respect to the number of cores. Another limitation is that the slice-based method is only applicable to the media content having selected video formats (e.g. MPEG-2, H.264) and not all the existing video formats.

Another known method for verifying the media content is an alternate parse decode method. In the alternate parse-decode method, the parsing of a current frame of the media content, and the decoding of a preceding frame of the current frame of the media content occurs simultaneously on the different cores. The alternate parse decode method is limited by the fact that it cannot scale beyond the two cores.

It has also been found out that in both the slice-based method and the alternate parse-decode method, the scaling is limited and applicable only for decoding of the plurality of frames of the media content while the video quality analysis of the media content occurs only in the single core. Based on the above, there is need for common methods and systems that will efficiently verify the media content with various formats.

Interaction among the system components of the system environment 100 is described later in conjunction with FIG. 2.

FIG. 2 is a block diagram illustrating a system 200 for performing verification on media content in accordance with various embodiments. In an example embodiment, the system 200 corresponds to a computing device such as, a Personal Digital Assistant (PDA), a Smartphone, a tablet PC, a laptop, a personal computer, a mobile phone, a Digital Living Network Alliance (DLNA)-enabled device, or the like. In another example embodiment, the system 200 may correspond to the first computing device 102, the second computing device 108, the first application server 106, the second application server 110, or the third application server 112.

The system 200 includes one or more processing units 202 a, 202 b, and 202 c (hereinafter referred as the processing unit 202), and one or more memory's 204 a, 204 b, and 204 c (hereinafter referred as the memory unit 204). The processing unit 202 is coupled with the memory unit 204. In one embodiment of the present application, the processing unit 202 is defined as a multi-core processing unit that includes three physical processing unit cores 202 a, 202 b, and 202 c, or simply three cores, where each of the physical cores is available to process at least one application thread concurrently with at least one other physical core processing another thread. It will be apparent to a person with ordinary skill in the art that the processing unit 202 may include any number of processing unit cores depending on the performance considerations.

The processing unit 202 is configured to execute a set of instructions stored in the memory unit 204 to perform one or more operations. The processing unit 202 fetches the set of instructions from the memory unit 204 and executes the set of instructions. The processing unit 202 can be realized through a number of processing unit technologies known in the art. Examples of the processing unit include an X86 processing unit, a RISC processing unit, or any other suitable processing unit.

In another embodiment, a computer application configured to execute on the system 200 includes at least one process (or task), which is an executing program. Each process provides the resources to execute the program, and one or more threads run in the context of the process. According to the present invention, a thread of the one or more threads is generally a basic unit to which the operating system allocates time in the processing unit 202. Each thread of the one or more threads may include a scheduling priority, thread local storage, a thread identifier, and a thread context (or thread state) until the thread is scheduled. In parallel applications, the one or more threads are concurrently executed on the processing unit 202.

The memory unit 204 is configured to store the set of instructions or modules. Some of the commonly known memory implementations can be, but are not limited to, a random access memory (RAM), a read-only memory (ROM), a hard disk drive (HDD), and a secure digital (SD) card. The memory unit 204 includes a program module 206. The program module 206 includes a set of instructions that are executable by the processing unit 202 to perform specific actions for performing the verification on the media content. It is understood by a person with ordinary skill in the art that the set of instructions in conjunction with the various hardware of the system 200 enable the system 200 to perform various operations. The program module 206 includes a processing module 210, a RAP module 212, a work-unit creation module 214, a demultiplexing module 216, a merging module 218, a report generation module 220, a loading module (not shown in the FIG. 2), and a communication unit (not shown in FIG. 2)

In one embodiment, the memory unit 204 acts as a medium that stores the data submitted from and/or required by the processing module 210, the RAP module 212, the work-unit creation module 214, the demultiplexing module 216, the merging module 218, the report generation module 220, and the loading module for performing the verification on the media content.

In one embodiment, the media content is stored as a file in the memory unit 204. In another embodiment, the media content may be stored at a server. The server may be positioned at a remote location, or locally where the verification of the media content occurs. The file is extracted by various modules mentioned above from the memory unit 204 or the server for performing verification on the media content in accordance with various embodiments.

The communication unit is configured for receiving the media content. In one embodiment, the media content is a fixed size static content. In another embodiment, the media content is a dynamically generated media content. The dynamically generated media content corresponds to the media content that is being continually filled with new data. In one embodiment, the communication unit receives the media content on a first thread of execution. The processing unit 202 a of the one or more processing units 202 a, 202 b, and 202 c is utilized on the first thread of execution. The present invention will now be described with an example where the media contents are generally provided as video contents. It should however be realized that the present invention can be used for other types of media contents, like for instance music contents, image contents, MMS contents, audio-video contents or the like.

In the present application, the communication unit is configured to communicate the media content to the demultiplexing module 216. The demultiplexing module 216 facilitates the demultiplexing of the media content into a video content and an audio content on the first thread of execution. The audio content partially corresponds to the video content. In the present invention, any suitable known technique is used in order to de-multiplex the media content into the video content and the audio content without resulting in the quality degradation of a digital video data and a digital audio data in the video content and the audio content respectively.

In one example, the demultiplexing module 216 divides the media content into a number of divided data portions, one for each type of data within the media content, namely the video content (corresponding to the digital video data) and the audio content (corresponding to the digital audio data). Thereafter, the demultiplexing module 216 outputs each of these divided data portions to the loading module. The loading module then facilitates the loading of the video content (corresponding to the digital video data) and the audio content (corresponding to the digital audio data) into their respective buffers that is: an audio buffer and a video buffer. In an embodiment, the audio buffer is capable of storing 10 kilobytes (“kB”) of Dolby Digital data or 8 kB of MPEG data, and the video buffer is capable of storing 500 kB of data. It is to be noted that the audio buffer and the video buffer may have any amount of space depending on the storage requirements without moving out from the scope of the disclosed embodiments. The loading of the video content and the audio content also occurs on the first thread of execution.

In the present invention, the loading of the video content and the audio content into the video buffer and the audio buffer respectively occurs continuously until the space in the video buffer and the audio buffer is full, or the video content and the audio content is over. In addition, the audio buffer and the video buffer are designed to be thread safe and are capable to handle multiple race conditions along with the read/write requests.

The audio content that is divided out from the media content and stored in the audio buffer may be encoded in a number of ways, such as MPEG, Dolby, PCM, etc., and may include the digital audio data for one or more audio channels, such as mono, stereo, five channel-surround sound, etc. The system 200 further includes the processing module 210 (herein configured to work as an audio processing module), to facilitate the processing (decoding) of the audio content using the appropriate decoding process. In an embodiment, the processing module 210 reads the audio content from the audio buffer, and then processes (decodes) the audio content on a second thread of execution. In the second thread of execution, the processing unit 202 b of the one or more processing units 202 a, 202 b, and 202 c processes (decodes) the audio content. The processed digital audio data is then converted into uncompressed form. In one embodiment, the second thread of execution on which the audio content is processed is different from the first thread of execution, but executes concurrently with respect to the first thread of execution. This implies that the first processing unit 202 a and the second processing unit 202 b are executing and processing simultaneously.

In the present application, the processing unit 202 b may utilize various coding techniques for decoding of the audio content into pcm samples.

In an embodiment, the video content (digital video data) that is divided out from the media content and stored in the video buffer is encoded in a number of ways, such as MPEG-2, H264 etc. Thereafter, the system 200 utilizes the RAP module 212, and the work-unit creation module 214 that facilitates the simultaneous processing (decoding) of the video content.

The demultiplexing module 216 of the system 200 is further configured to determine a format of the video content. The demultiplexing module 216 thus facilitates the parsing of the video content in order to determine the format of the video content. Further, based on the determined format of the video content, the RAP module 212 then facilitates an analysis of the video content. In the present application, the video content being analyzed for determination of the one or more random access points includes one or more video segments. Each of the one or more video segments includes the one or more video frames described above. In an embodiment of the present application, the one or more random access points are determined independently for each format of the video content. It is to be noted that the determination of the one or more random access points in the video content is dependent on the format of the video content. In the following paragraphs, the determination of the one or more random access points in the video content is described for MPEG2 format, H.264 format, and other intracoded formats (such as ProRES, DNxHD, and MJPEG2K).

In one embodiment, the video content is of MPEG-2 video format. In this case, the one or more video segments are identified from the video content. Here, one or more GOPs (group of pictures) are combined to form a video segment. Further, each of the one or more video segments is indicated by the presence of a header, and comprises a flag. In one example, the flag for each of the one or more video segments is represented as closed_gop. If the one or more video segments comprise the flag, then the one or more video segments are considered as closed one or more video segments. If the one or more video segments do not comprise the flag, then the one or more video segments are considered as open one or more video segments.

In case of the closed one or more video segments, each video segment of the closed one or more video segments is an independent sub-sequence, and there is no previous dependency of any current video segment of the closed one or more video segments on any preceding video segment of the closed one or more video segments. Thus, the RAP module 212 is configured to identify the one or more video frames that are positioned at the ends of the video segments of the closed one or more video segments as the one or more random access points.

In case of the open one or more video segments, each video segment of the open one or more video segments is not an independent sub-sequence, and there is dependency of any current video segment of the open one or more video segments on any preceding video segment of the open one or more video segments. In an embodiment, the dependencies can be handled by decoding one or video frames from a preceding video segment.

In another embodiment, the video content is of H.264 video format. Herein, the one or more random access points are identified by the RAP module 212 by facilitating an IDR (Instantaneous Decoder Refresh) technique. In the IDR technique, the one or more video frames are identified at which a decoder can be flushed and/or refreshed without any previous dependency.

In another embodiment, the RAP module 212 identifies the one or more random access points in the video content of the H.264 video format by facilitating a Recovery Point SEI Message technique. In the Recovery Point SEI Message technique, the RAP module 212 identifies the one or more video frames in which one or more messages are accompanied along with the one or more video frames at regular intervals as the one or more random access points.

In yet another embodiment, the video content is of intracoded formats (such as ProRES, DNxHD, and MJPEG2K). Herein, the video content comprises only I (Intra) video frames, and each of the one or more “I” video frames can be considered as the one or more random access points by the RAP module 212.

The RAP module 212 is further configured to identify one or more random access points in the video content on a third thread of execution. The processing unit 202 c of the one or more processing units 202 a, 202 b, and 202 c is utilized on the third thread of execution. In one embodiment, the third thread of execution is different from the first thread of execution and the second thread of execution, but executes concurrently with respect to the first thread of execution and the second thread of execution. This implies that the first processing unit 202 a, the second processing unit 202 b, and the third processing unit 202 c are executing and processing simultaneously.

In one embodiment, each of the identified one or more random access points corresponds to a first video frame of the one or more video frames of one of the one or more video segments in the video content. The RAP module 212 is further configured to obtain one or more details corresponding to the one or more video frames of each of the one or more video segments in the video content. The one or more details may correspond to a start time code, a starting picture number, a start content offset, an end time code or the like.

The system 200 further includes the work-unit creation module 214 configured for creating one or more work units. The work-unit creation module 214 facilitates the creation of the one or more work units on the third thread of execution based on the identified one or more random access points by the RAP module 212. In one embodiment, two consecutive random access points of the one or more identified random access points are used to create a single work unit of the one or more work units. In another embodiment, any number of random access points of the one or more identified random access points may be combined to form the single work unit of the one or more work units. The one or more created work units correspond to the one or more video segments. In one embodiment, the one or more created work units are stored in a job queue by the work-unit creation module 214. As soon as the work-unit creation module 214 creates the one or more work units, they are pushed into the job queue. The processing module 210 (herein configured as a video processing module) then reads the one or more created work units from the job queue. The processing module 210 facilitates the processing of the one or more created work units. The processing of the one or more created work units corresponds to the decoding and subsequently the quality checking of the one or more created work units. While the processing of the one or more created work units, each of the one or more video frames present within the one or more created work units is decoded and an output (decoded one or more video frames) is generated in the form of YUVs. After the decoding, if there is any change in the values of each of the video frames present within the one or more created work units that are processed, then type and description of errors like resolution, framerate, chroma format, or the like are notified on each video frames and sent to the report generation module 220.

In one embodiment, the processing module 210 facilitates the processing of the one or more created work units on one or more threads of execution in order to have better distribution of workload to utilize all the available computing power. In an embodiment, each of the one or more work units present in the job queue are automatically assigned to a free processing unit of the one or more processing units 202 a, 202 b, and 202 c. It will be apparent to a person with ordinary skill in the art that only three processing units are depicted in the one or more processing units 202 a, 202 b, and 202 c for simplicity, but it may include any number of processing units depending on the performance considerations. It is to be further noted that the one or more created work units are parallely assigned to the one or more processing units 202 a, 202 b, and 202 c depending on the format of the video data contained in the one or more created work units. In one embodiment, each of the one or more threads of execution is different from the first thread of execution, the second thread of execution, and the third thread of execution, but executes concurrently with respect to each other, the first thread of execution, the second thread of execution, and the third thread of execution.

The processing module 210 is further configured for determining one or more errors in each of the one or more work units being processed. In one embodiment, the determination of the one or more errors in one of the one or more work units being processed is facilitated by analyzing the one or more video frames in the one of the one or more work units. Also, the determination of the one or more errors in the one of the one or more work units being processed is also facilitated by analyzing the one or more video frames in a succeeding work unit of the one of the one or more work units. It is to be noted that each of the one or more determined errors is represented by its corresponding state information that comprises at least one of a type and description of error, a work unit identifier, a start location, and an end location. The type and description of errors may include resolution, contrast, framerate, chroma format, or the like.

FIG. 3 is a block diagram 300 illustrating determination of the one or more errors in one of the one or more work units being processed in accordance with various embodiments. As embodied and shown in FIG. 3, there are three work units being processed, namely, work unit (N−1), work unit (N), and work unit (N+1). It is shown that there are errors A, B, C, H, and I in the work unit (N−1), the work unit (N), and the work unit (N+1). For the determination of errors A, the processing module 210 will facilitate the analysis of the one or more video frames in the work unit (N). Similarly, for the determination of errors I, the processing module 210 will facilitate the analysis of the one or more video frames in the work unit (N−1). However, for the determination of the errors B, C, and H, the processing module 210 will facilitate the analysis of the one or more video frames in the work unit (N−1) as well as the one or more video frames in the work unit (N). It is to be noted that if an error is found at the boundary of the work unit (N−1) being executed at a processing unit X, then the processing module 210 will also facilitate the analysis of the one or more video frames in the succeeding work unit (N) being executed at a processing unit Y while analyzing the work unit (N−1) at the processing unit X in order to detect the errors.

Referring back to FIG. 2, the merging module 218, post the determination and identification of the one or more errors, then facilitates the merging of the determined one or more errors from each of processed one or more work units with each other based on the state information of each of the one or more errors. In an embodiment, the merging module 218 merges the determined one or more errors of similar type. Also, the merging module 218 combines the one or more errors beginning at one of one or more video frames of one of the processed one or more work units with the one or more errors continuing at least at a first video frame of one or more video frames of a succeeding work unit of the one of the processed one or more work units. The merging module 218 then stores the merged one or more errors from each of the processed one or more work units.

The merging of the determined error sequence from each of the processed one or more work units with each other will now be explained in conjunction with FIG. 4. FIG. 4 is a block diagram 400 illustrating merging of one or more errors in each of processed one or more work units in accordance with various embodiments.

In the work unit (N−1), a first error is found from a first video frame till a last video frame. In the work unit (N), the first error is found in a first video frame and a second error is found in last two video frames. In the work unit (N+1), the second error is found in a first video frame and a third error is found in last two video frames. Lastly, in the work unit (N+2), the third error is found in a first two video frames. The merging module 218 combines the first error till the last video frame of the work unit (N−1) with the first error at the first video frame of the succeeding work unit (N+1). The merging module 218 further combines the second error present in the last two video frames of the work unit (N) with the second error in the first video frame of the succeeding work unit (N+1). The merging module 218 further combines the third error in the last two video frames of the work unit (N+1) with the third error present in the first two video frames of the succeeding work unit (N+2).

Referring back to FIG. 2, the system 200 further includes the report generation module 220 configured for generating a verification report based on at least the merging and all the one or more errors that are found within the media content.

In an embodiment, the one or more random access points are identified by a RAP module 212. Firstly, the RAP module 212 is configured to determine a format of the video content by the parsing of the video content. Based on the determined format of the video content, the RAP module 212 then facilitates the analysis of the video content to identify the one or more random access points in the video content. In an embodiment of the present application, the one or more random access points are determined independent of a format of the video content.

In an embodiment, each of the identified one or more random access points corresponds to a first video frame of one or more video frames of one of one or more video segments in the video content.

At step 602, the media content is received on a first thread of execution. In an embodiment, the media content is received by a communication unit. In one example, the media content is a fixed size static content. In another example, the media content is a dynamically generated media content. The dynamically generated media content corresponds to the media content that is being continually filled with new data.

At step 604, the media content is demultiplexed. In an embodiment, the communication unit communicates the media content to a demultiplexing module 216. The demultiplexing module 216 divides the media content into a number of divided data portions, one for each type of data within the media content, namely a video content (corresponding to a digital video data) and an audio content (corresponding to a digital audio data).

At step 606, the video content and the audio content are loaded onto a video buffer and an audio buffer. In an embodiment, the demultiplexing module 216 outputs each of the divided data portions (the audio content and the video content) to a loading module. The loading module then facilitates the loading of the audio content and the video content to their respective buffers: the audio buffer, and the video buffer respectively. In one embodiment, the loading of the video content and the audio content onto the video buffer and the audio buffer occurs on the first thread of execution.

At step 608, the audio content is processed on a second thread of execution. In an embodiment, the audio content stored in the audio buffer is encoded in a number of ways, and may include the digital audio data for one or more audio channels. A processing module 210 (herein working as an audio processing module) facilitate the decoding of the audio content using the appropriate decoding process. In one embodiment, the processing module 210 (herein working as an audio processing module) reads the audio content from the audio buffer, and decodes the audio content on the second thread of execution. The second thread of execution is different from the first thread of execution but executes concurrently with respect to the first thread of execution.

The third thread of execution is different from the first thread of execution, and the second thread of execution, but executes concurrently with respect to the first thread of execution and the second thread of execution. The one or more random access points are determined independently for each format of the video content. It is to be noted that the determination of the one or more random access points in the video content is dependent on the format of the video content.

In an embodiment, one or more details corresponding to the one or more frames of each of the one or more video segments in the video content are also obtained by the RAP module 212.

In an embodiment, the processing of the one or more created work units by the one or more processing units 202 is facilitated by the processing module 210 (herein working as a video processing module). In an embodiment, the processing module 210 facilitates the processing (that is, the decoding and subsequently quality checking) of the one or more created work units on one or more threads of execution. While the processing of the one or more created work units, each of the one or more video frames present within the one or more created work units is decoded and an output (decoded one or more video frames) is generated in the form of YUVs. After the decoding, if there is any change in the values of each of the video frames present within the one or more created work units that are processed, then errors like resolution, framerate, chroma format, or the like are notified on each video frames and sent to the report generation module 220.

In an embodiment, each of the one or more work units present in the job queue is automatically assigned to a free processing unit of the one or more processing units. Further, each of the one or more threads of execution is different from the first thread of execution, the second thread of execution, and the third thread of execution, and executes concurrently with respect to each other, the first thread of execution, the second thread of execution, and the third thread of execution.

At step 616, one or more errors are determined in the one or more work units.
